Abstract: A charging device and method thereof is provided. The charging device is connected to a power supply device. The charging device includes a detection pin, a switch module, and a control circuit. The detection pin has a voltage level which reflects whether the charging device is connected to an electronic device. The control circuit is connected to the detection point and the switch module. According to the voltage level of the detection pin, the control module controls the switch module to be in an open state if the control circuit determines that the charging device is not connected to the electronic device.
